Orbital Services Program 4

The Orbital Services Program 4 (OSP-4) is a multiple-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract vehicle managed by the U.S. Space and Missile Systems Center to provide flexible small launch capabilities for government satellite and payload requirements. The program enables launch services for payloads ranging from 400 pounds to 8,000 pounds across various orbital destinations, including Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Highly Elliptical Orbit (HEO), and Geostationary Transfer Orbit (GTO). The contract supports both dedicated and primary launch services, with the potential for multiple launch vehicles to be used to meet specific mission requirements.

Task orders under OSP-4 typically involve launch service studies, mission integration, concept analyses, and specific mission task orders for satellite deployment. Prime contractors frequently include Rocket Lab, SpaceX, Blue Origin, Northrop Grumman, Firefly Aerospace, Astra Space, ABL Space Systems, and Relativity Space. Most task orders are firm fixed-price contracts with values ranging from $50,000 for minimum award studies to over $80 million for complex mission deployments. The majority of task orders are awarded by the Space and Missile Systems Center, with performance locations predominantly in California, Texas, and Arizona. None of the task orders reviewed utilized small business set-asides, despite the contract's openness to small business participation, and the contract vehicle supports national security space programs, scientific research, and technology demonstration missions.
